What Is Lamin Protein

The lmnagene provides instructions for making several slightly different proteins called lamins.

What is lamin protein.

Lamins are present in all animals but are not found in microorganisms. These proteins are made up of a nearly identical sequence of protein building blocks amino acids. There are several different laminins. Lamins line the inside of the nuclear membrane where they provide a platform for the binding of proteins and chromatin and confer mechanical stability.

The extracellular matrix ecm lies outside of cells and provides support and attachment for cells inside organs along with many other functions. Lamins have elastic and mechanosensitive properties and can alter gene regulation in a feedback response to mechanical cues. Lamins also known as nuclear lamins are fibrous proteins in type v intermediate filaments providing structural function and transcriptional regulation in the cell nucleus. The two major proteins produced from this gene lamin a and lamin c are made in most of the body s cells.

Laminin has arms that associate with other laminin molecules to form sheets and bind to cells. Laminin is defined by the webster medical dictionary as a glycoprotein that is a component of connective tissue basement membrane and that promotes cell adhesion in other words looking at laminin as a kind of glue isn t far from the truth. The lamins are the major architectural proteins of the animal cell nucleus.
